Abstract: The paper deals with the peculiarities of disintegrator milling, the development of disintegrator milling systems and the grindability of different metallic materials. In the first part of the paper the size reduction by collision is under consideration. A theoretical model for the size reduction of ductile materials by collision is proposed. The second part of the paper is focused on the development of disintegrators for processing of materials, which differs significantly from the other grinding equipment. The third part of the paper is focused on the disintegrator milling technology used for mechanical treatment of different metallic materials.

Keywords: disintegrator milling; disintegrator separation; metals recycling; metal powders; grindability; granularity; morphology; powder metallurgy; size reduction; ductile materials; grinding.
